Multi directional oscillation from a rotational source
View Patent ↗The present invention provides multi-directional oscillation from a rotational source, by receiving a rotational motion, converting the rotational motion to a first oscillating motion, converting the first oscillating motion to a second oscillating motion that is normal to the first oscillating motion and transferring the first oscillating motion and the second oscillating motion to a working element.
1. A method of multi-directional oscillation from a rotational source, comprising:
receiving a rotational motion from a rotary tool element;
converting the rotational motion to a first oscillating motion about an axis;
converting the first oscillating motion to a second oscillating motion axially along the axis, wherein converting the first oscillating motion to the second oscillating motion is accomplished by moving a working element coupling along a longitudinal axis of a shaft, the shaft transferring the first oscillating motion about its longitudinal axis to the working element coupling, the working element coupling being moved by an interaction of a first ramp of the working element coupling and a second ramp, the second ramp disposed to interact with the first ramp first oscillating motion to cause the second oscillating motion; and
facilitating application of at least one of the first oscillating motion and the second oscillating motion to a working element.
2. A rotary to multi-oscillating system, comprising:
a first oscillating motion system for producing a first oscillating motion from a rotational source, comprising:
an off-centric ball bearing receiving a rotational motion from the rotational source;
a cam interacting with the off-centric ball bearing to cause a shaft to oscillate about its longitudinal axis; and
a second oscillating motion system for producing a second oscillating motion from the first oscillating motion of the shaft, comprising:
a linear bearing with a first ramp, the linear bearing receiving the first oscillating motion from the shaft and disposed to move along the shaft; and
a multi-oscillation generating ramp disposed relative to the first ramp so that the first oscillating motion of the linear bearing cause the first ramp to interact with the multi-oscillating ramp resulting in the linear bearing moving along the shaft in a second oscillating motion.
3. The system of claim 2 , further including a spring disposed within the linear bearing to facilitate the linear bearing stably moving along the shaft in the second oscillating motion.
4. The system of claim 2 , further including a working element attached to the linear bearing for receiving the first oscillating motion and the second oscillating motion.
